@arcjet/logger

@arcjet/logger

Arcjet lightweight logger which mirrors the Pino structured logger interface.

• npm package (@arcjet/logger)
• GitHub source code (logger/ in arcjet/arcjet-js)

What is this?

This is an internal utility to help us log things. It provides a small interface, a bit like Pino, so that users with custom needs can swap it for their own logger.

When should I use this?

You should probably not use this but use one of the alternatives instead. This package matches our current needs which are likely different from yours.

Install

This package is ESM only. Install with npm in Node.js:

npm install @arcjet/logger

Example

import { Logger } from "@arcjet/logger";

const logger = new Logger({ level: "debug" });

logger.debug("only printed in debug mode");
// Logs ✦Aj DEBUG only printed in debug mode

logger.error("%d + %d = %d", 1, 2, 3);
// Logs ✦Aj ERROR 1 + 2 = 3

Log levels

Log levels can be changed by setting the ARCJET_LOG_LEVEL environment variable to one of: "DEBUG", "LOG", "WARN", or "ERROR".
